My invention relates to certain types of printing devices permitting the reproduction of individual prints selected out of a vchain or band of type plates commonly used in con-l f nection with addressing or similar devices.

One object of my invention is to provide a specially designed print duplicating device wherewith any desired member in a chain of suitable type plates may be inserted and printed without the necessity of detaching or 5 causing not only a considerable loss of time but also tends to confuse the system of arrangement in the chain.

These and other objections I overcome by my novel printing device composed of various parts and elements fully described in this specification and illustrated in the acconipanying drawings in which:

Figure 1 represents a partly sectional front elevation of such a printing device, enibodying the features of my invention.

Figure 2 represents a. partly sectional plan view of the printing portion of the device, along lines 2-2 in Figure 1.

Figure 3 represents a plan view of complete device.

Figure 4 represents a partly sectional side view of Figure 3, along lines 4 4.

Figure 5 represents a detailed view of a chain of type plates, as commonly used in connection with addressing and similar duplicating devices.

Figure 6 represents a side view of the chain of type plates shown in Figure 5.

Similar numerals refer to similar parts throughout the drawings.

Upon `a common base plate a, shown in Figures 1f and 4, the stationary supporting member b is rigidly mounted vand held in posi.- tion: by'V afpair Aof suitable `studs kvc and c1.

Member b is provided with` a bearing. b1 serving as a pivot forthe operating lever d, which in turn is movably interconnected with a plunger e, by means of a slot Z1 and pinel. Plunger e being slidably guided in support- `in g memberb, is normally held in its upward 'M position by a, preferably conically wound, coil spring f pressing against collar e2 which forms a part of plunger e. The lower part of plunger e is shaped into an elongated rectangular head e3 whose function is to perform the printing operation described further below. A cage 'comprising the two lower prongs z' and the two upper prongs '51, rigidly held together, is securely mounted upon the rectangular plunger head e3. This cage l -serves the purpose of engaging 'and holding the type plates-Z in position. A platform g,

the centra-l portion of which is suitably ycut out, is yalso rigidly mounted upon plunger Yhead e3.- Screws 7c serve the purpose of securely mounting cage members z', l and platform g upon head e3. (See also Fig. 4.) y

The type plates, as shown in Figures 5 and 6,' are suitably linked together and present a chain, which Vin turn may be wound and yunwound upon suitable spools, not indicated in the drawings. f

A centrally positioned padded stem L is removably held in position by suitable supports km and m1, also mounted upon base' a.

v The inking ribbon n may be conveniently wound .or unwound upon removably arranged spools o and 01, supported in brackets o2 and '03. Theribbon n, spools 0 and bracket 02 are of conventional kdesign and do not form-a part of this invention and for this reason need not be described in detail.

f The device is functioning as follows:

After selecting the type plate of which a duplicate print is to be made and vwithout detaching the saine from the chain it is inserted into the cage, that is between the lower prongs z' andthe upper prongs il, as clearly indicated in` Figure 1. f A i ,y Anenvelopeoranyother.suitable medium upon which a print is to be reproduced is then inserted into the gap formed between platform g and the padded'stem h. Vith these members now in position the plunger e is forced downward by means of the manually operated lever fl, whereby plunger head e3 and cage i and l are forced against the envelope or otherl medium. Now by means of the interposed inking ribbon a clear iin-y print is produced upon the medium. This printino' operation, of course, can be repeated as often as desired or another type plate inserted as described above.

Having thus fully described my invention I do not wish to limit myself to the exact details of construction as disclosed in this form of embodiment, it being apparent that there may be considerable variations in the design Aof this device without departing from the spirit of my invention.

What I claim as new and desire to secure by Letters Patent is:

l. In a device of the character described, a movable printing member, manual operating means for said printing member, suitable type plate engaging and holding means forming a part of said printing member, a suitably arranged platform also forming a part of said movable printing member to serve the purpose of supporting and guiding an inking band and to actuate in unison with said printing member substantially as and for the purpose set forth.

2. In a device of the character described, a movable printing member, and manual operating means for said movable printing member, said printing member comprising a suitably shaped plunger whose lower or operating portion is provided with a suitabletype plate engaging and holding means and a suitable platform also to form a part of said plunger for the purpose of supporting and guiding an inking band and to actuate in unison with said printing member, substantially as and for the purpose described.

3. In a print duplicating device of the character described, a movable printing member, manually actuated operating means for said movable printing member, and said movable printing member comprising a suitably shaped stem whose lower or operating end is shaped into a suitable head upon which a plurality of suitable type plate engaging and holding members and a suitable inking ribbon-platform are mounted and operated in unison with said stem, substantially as and for the purpose set forth.

4. In a print duplicating device of the char- .acter described, Va slidably arranged printing plunger, the lower or operating portion of said sliding plunger forming a suitable head, supporting and holding a plurality of type plate engaging prongs and a suitable platform for the purpose of supporting and guiding a suitable inking band and said type plate Signed at the city of New York in theV county of New York and State of New York June, A.
